Question - 50 : - Why Xaml in Xamarin.Forms?
Answer - 50 : -
- XAML(Extensible Application Markup Language) allows developers to define user interfaces in Xamarin.Forms applications using markup rather than code.
- XAML defines the visual appearance of a UI, and an associated code-behind file defines the logic. The UI design can be adjusted without necessarily making changes to the logic in code-behind. XAML in this role simplifies the workflow between individuals who might have a primary visual design responsibility and individuals who are responsible for app logic and information design.
